Birds
The TRUE VULTURES (_Vultures_) have stout powerful bodies, which are of
unusual breadth at the breast; the wings are long, broad, and rounded,
their fourth quill being of greater length than the rest; the tail is of
medium size, and slightly rounded at its extremity; the individual quills
are stiff and ragged, or split towards their tip; the legs are strong,
of moderate length, and destitute of feathers; the toes, though long
and powerful, are almost useless for grasping; the talons are slightly
bent and very blunt. The beak, which is as long as the head, is higher
than it is broad, and straight except at its extremity, which terminates
in a moderately long and very sharp hook; the mandibles bulge slightly
outwards at their margins. The plumage is composed of very long and broad
feathers, and does not entirely cover the body, the head and neck are
either quite bare or overspread with a slight growth of hair-like down.
In some species the legs and belly are covered with down, intermingled
upon the latter with long narrow feathers. The bare or thinly-covered
portions of the body are often brightly coloured, but the plumage itself
is usually sombre and indistinct in its coloration, though occasionally
variegated. The eyes are large and expressive, the formation of the
nostril differs considerably according to the species. All the members
of this group see, hear, and smell with great acuteness, and their
intelligence is by no means inferior to that of the Bearded Vulture.

The CONDORS, or WATTLED VULTURES (_Sarcorhamphi_), as three of the
largest species of True Vultures have been called, are at once
recognisable by their comparatively slender bodies, long narrow wings,
and long tails. The tarsi are high and the toes large; their neck is
of moderate size, and the head long; the beak, compressed at the side,
terminates in a powerful hook, which, in the male, is decorated above
the base of the upper mandible with a kind of fleshy comb, and, in the
region of the chin, with wattles or folds of skin. The nostrils are very
peculiar in their formation, not having the usual division between them.
The plumage is composed of small, brightly coloured feathers, and does
not cover the whole body, some parts being left entirely bare. Unlike
most of their family, the males of the three known species of Condors are
larger than the females.
